Summary of Test Method4.1 Test specimens are g

17、enerated of an image described inthis test method. Suitable hard copy Abrasion Test Targets foruse in copiers are available from ASTM. Abrasion test targetsmay be converted into digital files for use in computer printers.The specimens are abraded with a specified instrument andevaluated by visual co

18、mparison or reflectance measurements,or both.5. Significance and Use5.1 The degree of image abraded from a copy or printedimage may be affected by various factors, including the type ofmachine, condition of the machine, supplies employed, timesince imaging, and environmental conditions. As many aspo

19、ssible of these variables should be controlled during the test.If available, a control sample with known characteristicsshould be run along with the test samples.5.2 This test method may be used to determine imageresistance to damage or deterioration as a result of exposure toabrasive forces, such a

20、s automated document handling devices.5.3 This test method may be used for control of productquality, comparative analysis of machines, comparative analy-sis of imaging components, as well as a research and develop-ment tool.5.4 This test method is adaptable to images produced frommost nonimpact pri

21、nters and copiers. The printers shall becapable of utilizing the available program to produce thespecified image.5.5 If the user wishes to simulate the type of damage orsmudge resulting from paper rubbing against the printed imageor from normal handling, consideration should be given tousing either

22、the Crockmeter Method (Test Method F1319)orthe Sutherland Rub Method (Test Method F1571 or PracticeF2497).6. Interferences6.1 The degree of image fixing is an integral factor in theresistance of the image to damage or deterioration due toabrasion. The image fixing capabilities of copiers and printer

23、smay be significantly influenced by the choice of supplies. Toobtain an accurate representation of the capabilities of anygiven machine, the manufacturers recommendations for toner,fusers, fuser oils, other imaging supplies, and paper should befollowed.6.2 Due to the temperature cycling of some copi

24、er andprinter fuser systems, the degree of image fixing may vary asa function of the length of time the machine has been turned onor as a function of the number of copies or prints in a given run.NOTE 1For example, the degree of image fixing may be different forthe first few copies made right after

25、the machine is turned on than it willbe for the copies made several hours later. Also, the fiftieth copy of a runmay have a different degree of fixing than the second or third copy of thatsame run.6.3 Unusual environmental conditions, such as extremes oftemperature and humidity may affect both the d

26、egree of imagefixing and the copy quality. For this reason, it is recommendedthat the environmental conditions be noted when conductingcomparison tests between machines or supplies. For the mostaccurate comparisons, the environment should be kept asconstant as reasonably possible during the entire t

If a copier or printer is to be used to evaluate a supplyitem, all other supply items should be unchanged during theduration of the comparison test.7.7.1 If comparison tests are being made between copier

36、s orprinters, all supply items should be as specified by themanufacturer. Unless otherwise specified by the manufacturer,the same paper should be used in each of the machines.7.8 Abrasion Test TargetA printed Abrasion Test Target isavailable as an ASTM adjunct. Fig. 1 shows a printed exampleof the t

37、arget.7.9 ReflectometerAn instrument for the measurement ofreflection density meeting the geometric conditions for reflec-tion density specified in ISO 5-4, the spectral conditionsspecified in ISO 5-3, and having an aperture diameter of10 mm.NOTE 3An aperature of 10 mm will cover the entire area of

38、the testspot. If an instrument with a smaller aperature is used, several readingsshall be taken and averaged to obtain the reflectance of the spot.7.9.1 Measurement should be reported as percent reflec-tance. If the instrument reads in optical density, convert thevalues to reflectance, as follows:R,

39、%reflectance! 5110Ddensity!3100 (1)A scientific calculator may be used to aid in this conversion.8. Preparation of Apparatus8.1 Copier or PrinterEnsure that the test copiers orprinters, or both, have been properly adjusted following themanufacturers instructions. Ensure that an adequate amount ofall

40、 supplies needed for operation conforms with the manufac-turers specifications and is in a quantity adequate to completethe test without replenishment. If replenishment is necessary,make certain that it is from the same lot.8.2 ReflectometerWarm the instrument up and calibrate itin accordance with t

41、he manufacturers recommendations.Check calibration frequently while making measurements.8.3 Abrasion Tester:8.3.1 Prepare abrasive wheels by conducting two indepen-dent dressings of 50 cycles each on a 150-grit abrasive disc,discarding the used abrasive disc after each dressing operation.If a thin f

42、ilm of material develops on the edge of the wheelsduring dressing, it may be removed by gently rubbing with afinger while rotating the wheels by hand on their spindles.Avoid touching the abrading surfaces of the wheels.8.3.2 Place the 500-g auxiliary weights onto the pivotedarms.8.3.3 Attach the vac

43、uum source to the abrader and set thevacuum level to 100 % to allow for effective particle removalwithout lifting or damaging the specimens. Set the vacuumnozzle height to 3 mm above the specimen surface.8.3.4 Blow particles off from wheels after abrasion of eachspecimen.8.3.5 Dress wheels 50 cycles

44、 with a new 150-grit abrasivedisc after every four specimens.NOTE 4Discoloration of the abrasive wheels with image material doesnot necessarily indicate dirty or ineffective wheels.8.3.6 Should either wheel become out-of-round, it will benecessary to simultaneously reface both wheels using thediamon

45、d wheel refacer. Out-of-round wheels are indicated by aslight up and down motion of the pivoted arms as the wheelsrotate on the specimen. Refacing must continue until bothwheels are again round.NOTE 5Observe the wheel manufacturers recommendations withrespect to minimum wheel diameter and maximum sh

46、elf life. Store wheelsin their original protective case when not in use.8.3.7 After wheels have been refaced with the diamondwheel refacer, it is necessary to dress them once using 50cycles on a new 150-grit abrasive disc.9. Procedure9.1 This test method may be used to either make a com-parative eva

47、luation between two or more printers or copiers orto evaluate a supply item for a printer or copier. Whenevaluating a supply item, a single copier or printer shall beused and all other supply items shall remain constant. In anyevent, the procedure for sample generation and selection,abrasion testing

48、, and evaluation is the same.9.2 Sample Generation and Selection:9.2.1 Turn the copier or printer on for 30 min and ensurethat the machine has been idle in “standby” mode for at leastfive continuous minutes immediately before the test has begun.9.2.2 Generate test copies or prints using a suitable a

49、brasiontest target in the case of a copier, or computer program in thecase of a printer.9.2.3 Run the copier or printer in continuous mode for 2 minto ensure a representation of the varying degrees of toner fixingthat may occur within a given system. Save all copies or prints.Maintain them in the sequence in which they were generated.9.2.4 For machines rated at less than 40 copies per minute,select sample sets of three consecutive sheets from thebeginning, middle, and end of the run. For machines rated at 40or more copies per minute, select
